Question

question 8 of 50
which increases speciation?
a. no competition
b. lack of mutations
c. low gene flow
d. asexual reproduction

Explanation:

Speciation is the process of forming new species. Low gene flow reduces the exchange of genetic material between populations. This allows populations to evolve independently, accumulating genetic differences over time. These differences can lead to reproductive isolation and the formation of new species. In contrast, no competition (A) doesn't directly drive speciation as it doesn't create barriers or genetic divergence. Lack of mutations (B) would slow evolution as mutations are a source of genetic variation. Asexual reproduction (D) limits genetic diversity compared to sexual reproduction, which is less conducive to speciation. So, low gene flow (C) increases speciation.

Answer:

C. Low gene flow
